Can you look at the actual email source? I'll bet that the attachment is labelled text/plain rather than text/html. That would probably be done upstream -- its a common tactic called defanging mime types.


--Apple-Mail-18--376424074
Content-Transfer-Encoding: 7bit
Content-Type: text/plain; charset=US-ASCII; format=flowed

This is similar to what you will see -- I will bet that the header just prior to the email newsletter is getting set to text/plain on your system rather than the default setting of text/html.

This is typically a mail server issue.
